Description
Cock plugs in PTFE with a polypropylene retaining device form a complete stopcock plug assembly for laboratory glass joints of size 12.5 and a bore diameter of 2 mm. The PTFE plug body provides a chemically resistant sealing surface suitable for many common laboratory media, while the PP retaining device holds the plug securely in the joint during operation and storage. This complete unit is intended for glass stopcocks and related fluid-control components used in distillation, extraction and general laboratory glassware setups. The defined 2 mm bore supports controlled flow through the stopcock channel when the plug is correctly oriented. Pack size is 2 pc(s), with a unit weight of 0,001 kg, allowing compact stocking for maintenance and replacement needs. These cock plugs with retaining device from manufacturer Bohlender are supplied ready for installation on matching joint 12.5 stopcock bodies. They serve analytical, preparative and teaching laboratories that require PTFE plug inserts combined with a practical PP retention system for everyday glass apparatus work.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Cock plugs, PTFE, retaining device of PP, for joint 12.5, bore Ø 2 mm, complete
What is this article?
Cock plugs, PTFE, retaining device of PP, for joint 12.5, bore Ø 2 mm, complete is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
